SPECIFICATION forming part of Letters Patent No. 467,968, dated February2, 18.92.

Application 'filed March 4, 1891. Serial No. 383,797. (No model.)

shape of cylinders for Wagons, carriages, buggies, and all kindsof'vehicles, all of which is shown' in the accompanying drawings, andletters and figures marked thereon, which form a part of thisspeciication.

My said invention is applicable to all kinds of revolving journals,shafts, and spindles, whereby the friction incident to'the revolution ofsuch journals, shafts, and spindles is very materially lessened and thedurability very much increased thereby; also, the amount of oil and thefrequency of its application is verymuch lessened.

Figure 1 is a view showing the exterior construction of same in threepieces or sections, together with the'bearings, as shown in cylinderforin,"Fig. 3, having conical-shaped ends. They are to be made oftempered steel and vplaced in each end of the'box, (which box `is to bemade of cast-iron), to Wit: (a) in sections 1 and 3, 2, Where they areheld in place by a flange or rim While the lbox may be taken from thejournal, shafthor spindle. Further, the bearings rest on the interiorwall of the box, as shown in Fig. 4. This allows a ready revolvingmotion of ,same when brought in contact with the journal, shaft, orspindle and thereby lessens the4 draft. Section 2 or the center sectionof,the Vbox does not come in contact with the journal, shaft, orspindle, -but is heldat a respectful distance by the bearings, as shownin Fig. 5.l

Sections l and 3 are made to join by means of l screw applications tosection 2, as shown in Fig. 2. The .same may easily be detached and thecylinders removed. Whenl joined together with the cylinders inclosed, 1tmakes Fig. 2 shows the interior ofv a neat and compact box. The exteriorWall of the box is the same size at each end, as shown in Fig. l,instead of being larger'at one end and smaller at the other end, as inthe ordinary box. each end is also the same size as shown in sections land 3, Fig. 2, hence requiring the The interiorof the box at.

shaft or spindle to be the same diameter at the shoulder as at the outerend of saine. There is a rim on -each end of the box. extends over theshoulder on the spindle and the other over the-nut on outer end of same,

One

as shown in Fig. 2, thus keeping out dust, &c.

The box is placed on .the inside of hubs of Wagons, carriages, buggies,and other vehicles,

-the same as the ordinary box. The oil is apspindle as in c Having fullydescribed my invention, what I claim, and desire to obtain by LettersPatent is- 1i The combination, with the hub of Wheels of wagons,carriages, buggies, and other vehicles, of a box therein consisting of aseries of three threaded sections, the two end sections having a flangeor rim which forms a groove on the interior Wall of the out ends ofsame, and theV center section having a flange-or rim on each end of samewhich forms agrooveand contains and holds in place, when fastenedtogether, a ring ofsmall cylinders with conical-shaped endslongitudinally located in each end of said box, subst-antially-as setforth.

2. The combination, with the hub of wheels of wagons, carriages,buggies, and other vehicles, of a removable box inserted therein,consisting of a series of three threaded sections, the two end sectionshaving a iiange orv end of same .which forms a groove and holds -inplace when'fastened together a ring ofV anti-friction cylinder-bearingswith conicalshaped endslongitudinally.V located in each end of said box,substantially as' described.

3. The combination, with the hub of wheels of' wagons, carriages,buggies, and, other vehicles, of a box therein inserted consisting ofthree threaded sections 1 2 3, having a ring of anti-frictioncylinder-bearings with conical-shaped ends contained and held in place Yin each end of said box longitudinally by the iangev or rim on each` endof the center section, which formsa groove when said sections .to arejoined together, and the flange or rim.

which forms a groove on the interior wall of the outer end of each 0fthe end sections of said box, substantially as described and sct forthin the foregoing drawings and specilication.
